A new squirrel themed capsule machine has appeared in Delta Island Garden Shop, it offers 16 prizes and I personally like this one more than the Turtle machine.
Took me about 90k~ gralats to collect them all and a few others have reported going 50k+ but some will get luckier than others.
Here are pictures of all the prizes:
Hats:
Furniture:
Remaining prizes include a squirrel morph, bomb, juggle, accessory, & banner(food is just Acorn x5 not going to include it as prize):
